minifyEnabled true导致应用启动时崩溃

问题描述

设置后，启动生产应用后，我会立即收到此消息

I receive this message as soon as I start my productive app, when I set

buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

我没有任何其他保护规则(因为没有图书馆指出这是必要的).

I do not have any additional proguard-rules (cause no library stated that it is necessary).

我的依赖项如下:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.loopj.android:android-async-http:1.4.9'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'
    compile 'com.google.android.gms:play-services-gcm:8.4.0'
    compile 'com.google.android.gms:play-services-ads:8.4.0'
    compile 'me.leolin:ShortcutBadger:1.1.4@aar'
    compile 'com.facebook.android:facebook-android-sdk:4.+'
    compile 'com.jraska:falcon:1.0.0'
}

我试图添加

-keep class com.loopj.** {*;}
-keep class com.jraska.** {*;}
-keep class me.leolin.** {*;}
-keep class com.android.** {*;}
-keep class com.google.** {*;}
-keep class com.facebook.** {*;}

到我的保护规则，但仍然是相同的错误.有什么主意吗?

to my proguard-rules, but still the same error. Any idea?

推荐答案

所以我在日志中发现了错误

So I found the error in the log

W/SupportMenuInflater(29041): Cannot instantiate class: android.support.v7.widget.SearchView
W/SupportMenuInflater(29041): java.lang.NoSuchMethodException: <init> [class android.content.Context]

添加后

-keep class android.support.v7.widget.SearchView { *; }

到我的proguard-rules文件中，一切都按预期工作.

to my proguard-rules file, everything worked as expected.
